Packaging Maker Offering Tamper-Evident RFID Film
Pliant, a $2 billion manufacturer of packaging products, says it has developed an RFID-enabled stretch film. The company claims its customers—which include the U.S. Department of Defense (DOD), as well as pharmaceutical and consumer packaged goods companies—could use the product not only to comply with government or retail RFID mandates, but also to determine whether individual pallets have been tampered with.
Stretch film, also known as stretch wrap, is a clear polyethylene film that clings to itself and typically is used to bind a number of small, individual cases together to create a larger unified load, such as a pallet. Pliant has worked with nanoparticle materials company NovaCentrix to devise a means of printing an electrically conductive trace into its stretch film using NovaCentrix's silver ink. The conductive trace is printed in two parallel lines, 6 inches apart and 1 to 1.5 inches wide.
